The New York Evening Post of Saturday says: "This morning a statement was authorized ,that a general consohdatioii of the various air power interests is in contemplad on and itbat the American Air Power Co,, of jthis city, will practically absorb all the otber concerns The W. C. Whitney syndicate has jnst secnred control of the American Air Jfower Co. Upon the report of President Vreeland, of the Metropolitan Railroad Co., in regard to the efficiency of the air power cats on the Twenty-third st. line, which have been in operation during the last fonr months. it has been decided to equip immediately all the downtown crosstown lines with air as a motive power, i and also the belt lines, where it is impossibleTto install a condnitj for an underground circuit. The Whitney syndicate, which control the uorth and west side iChicago lines, is now having plans prepared and contract drawn f; to ï'equip ,"the lines at present operated by cable in Chicago, with the Hadley-Knight compressad air systein. The American Air Power Co., it is said, have secured also frorn the International Power Co., of Providence, the right to use 'the Jatters' plant in the manufacture of automobiles." This is important uews in this sectiou, where so rnany railway projects have been held back awaiting the development of compressed air as a motive power for street cars. If the experience of the New York and Chicago lines indícate that this power is feasible and economical, two lines from this city will be at once constructed ; one to Jackson by way of Dexter and Chelsea and the otber to Detroit through Superior and Plymouth. One thing which has kept these lines from being built this snmmer is the high price of copper wire, together with the advance in iroD. With the new power, the pules and overhead fixtures will be done away with so that the cost of coustructiug Iod;: lines of street" raihvays will be matenally reducea. The prouioters of the new liues did uot desire to take auy chances equippiug expensive lines with electricity whicn might iu a yéar be reudered an obsolete power.
